IMPROVEMENT IN DOOR OR SHUTTER FASTENERS.

Specification forming part of Letters Patent No. 123,816, dated February20, 1872.

To all whom it may concern:

Beit knownthat I, WM. FIELDS, of Wilmington, Delaware, have inventedcertain new and useful Improvements in Door and Shutter Fasteners, ofwhich the following is a specilication:

The nature of my invention consists in the construction of a .device forholding a door wide open and shutters back in position after they havebeen once opened, as will be more fully described hereafter and setforth in the claim.

In the accompanying drawing, Figure l isa side elevation of my inventionas shown attachedto the shutter in a closed condition. Fig. 2 is a planview of the stop. side view of my invention, showing the position of thevarious parts when the shutter is open.

A represents a common windowfra1ne,in tended for one or two shutters, B,as may be desired. Secured to the sill C is ametallic stop, D, having,preferably, an inclined circular surface upon its top, and which is cutaway at its outer end, so as to form an abrupt shoulder, a. Secured tothe lower edge ofthe shutter is a hinged metal plate, G, which isattached by means of a staple or some similar device, or is hingedto-another plate in such amanner that it has a free verticahmovement.While the shutter is closed, this plate rests upon the top of the stopD, as shown in Fig. l, and is pressed up against the edge of the shutter5 but as soon as the shutter is thrown open, the plate Fig. 3 is aslides over the top of the stop, until the end has passed the shouldera, when it at once falls from its own weight, so that its end, restingagainst the shoulder, forms a sure and effective guard against theshutter being closed until the end is raised by means of the catch orhandle b provided for that purpose.

The advantages of my device are many and obvious. It is exceedingsimple, consisting of but two pieces, that cannot get out of repair, ischeap, and does not require the services of a skilled mechanic to attachit, and, being attached to the inner corner of a shutter, a persondesiring to close the shutter does not have to lean out of the window toreach it. Instead of the stop being of the form and shape shown, I mayuse any other one so constructed that it will present a shoulder,against which the end of the" plate G can rest, so as to hold theshutter in place.

Having thus described my invention, what I claim, and desire to secureby Letters Pat-
